Echo-Echoflex Interface LED status blink during firmware upgrade

Description

The Unison Echo®-Echoflex interface (EEI) uses a MicroSD card for firmware upgrades.  At the beginning of an upgrade, the EEI will blink its status or error lights in different patterns, depending on what is happening. 

State

Status LEDs

Error LED

Bootloader resident

Blink, blink, none, none

Off

Writing firmware to flash

Blink, blink, blink, none

Off

Bootloader error

Off

Blink, blink, none, none

Flash checksum error

Off

Blink, blink, blink, none

SD Card Error

Off

Blink, none, none, none

While the upgrade is happening, the Status LEDs will blink (as per "Writing firmware to flash" above) and the LED bar graph will light up sequentially.  This process typically takes less than a minute.

When the upgrade is successful, the EEI will return to normal mode.  Be sure to remove the MicroSD card at that point.
